BYRON PHELPS, OF SEATTLE, WASHINGTON.

LOCK.

5PEGIFICATION forming part of Letters Patent No. 722,620, dated March 10, 1903. Application filed September 23, 1901. Serial No. 76,311. (No model.)

To to whom it may concern:

Be it known that I, BYRON PHELPS, a citizen of the United States, residing at Seattle, in the, county of King and State of Washington, have invented a new and useful Look, of which the following is a specification.

My invention relates to locks, and particularly to a class of locks wherein all of the mechanism is carried by a single frame,which is adapted to be inserted in a'notch in the stile Of a door.

The object of my improvement is to furnish a lock the bolt of which may be operated by a key from both sides of a door, and in accomplishing this object to attain a maximum degree of simplicity and strength, as well as compactness.

Further advantages of my improved lock will readily suggest themselves to one skilled in the art.

Figure 1 is a plan view. Fig. 2 is a view, partly in section, taken through Fig. 1 on line X X looking in the direction of the arrow. Fig. 3 is a detail of detached portions.

A is a frame formed, preferably, of one piece and is fully described and broadly claimed in a former patent of mine, No. 631,432.

B B are extensions or sleeves upon the frame A. Journaled within the sleeves BB are spindles O 0, provided with knobsD D, respectively. These knobs are in this embodiment hollow, and each contains a key mechanism E E. These key mechanisms may be of the ordinary pin-tumbler type well known in the art and will not be particularly described.

F is a roll-back carried in a notch in the end of the spindle C. F is another roll-back carried in a notch in the end of the spindle C.

G is a yoke having arms G G2 and a shank G The shank G is pivotally attached to a swinging latch-bolt H.

J is a spring carried on the shank G and interposed between the latch-bolt H and a portion of the frameA and serves to keep the latch-bolt, and with it the yoke G, in the position shown in Fig. 1, in which position the arms G G are in contact with roll-backs F F.

-When either spindle is rotated, its attached roll-back bearing against one of the arms G G draws back the latch-bolt H.

Kis locking-bolt having a shank K, Fig. 1. The shank K is provided with a groove K L is a rock-shaft journaled in the frame A and having arms L L The arm L has a pin L which projects into the groove K When the rock-shaft L is rocked, the pin L bears against one side of the groove K and slides the bolt in or out, according to the direction of motion ofthe rock-shaft L.

M is a reach-rod, one end of which is attached to the arm L The other end of the reach-rod M has projections I M N N are rotatable rods which lie in the center of the spindles O C, respectively. One end of the rod N is engaged with the key mechanism E, while its other end carries an actuating-dog N One end of the rod N is engaged with key mechanism E, while its other end carries an actuating-dog N These rods when in normal position have the position shown in Fig. 3. Both dogs N and N lie directly under theprojections M and M and when one or the other is rotated it bears against the projection M or M according to the position of the reach-rod M. In throwing bolt K into the position shown in dotted lines the dog N would be rotated (clockwise in the drawings) until it struck the projection M Further movement would then cause the reach-rod M to be advanced, thus rocking the shaft L, causing the pin L to bear against one side of the groove K and thereby advancing the bolt K. In retracting the bolt K dog N would be rotated counter-clockwise until it engaged projection M, and continuedmovement would throw the reach-rod M to the left and through the medium of the rock-shaft L retract the bolt K. In order to withdraw the key, the dog N would be rotated still farther in either of the above cases until it assumed the position shown in Fig. 2, at which position the key mechanism would release the key.

The dog N operates the mechanism precisely the same as above described for dog N but is operated from the outer knob and key mechanism E.

Both roll-backs F F have central openings, allowing free rotation of rods N N and also permitting free movement of the roll-backs.

It will be seen that the locking mechanism in this embodiment applies alone to the bolt K, the latch-bolt H being always free to be operated by turning either knob and actuating it through the roll-backs, as previously described.

P is a flat spring which yieldingly holds rock-shaft L in its extreme positions.

It is obvious that many changes may be made in the particular construction without departing from the spirit of the invention as defined in the claims.

What I claim is 1. In a look, a frame, an outer and an inner spindle, a latch-bolt and mechanism for operating the same, a locking-bolt, a reachrod extending from said bolt to a point adjacent the inner end of both spindles, a key mechanism having a connection through said outer spindle with said reach-rod, and another key mechanism having a connection through said inner spindle with said reach-rod.

2. In a lock, a frame, an outer and an inner spindle, a latch-bolt and mechanism for operating the same, a locking-bolt, a reachrod extending from said bolt to a point adjacent the inner ends of both spindles, a key mechanism having a connection through said outer spindle with said reach-rod, and another key mechanism having a connection through said inner spindle with said reach-rod, both of said connections being normally disengaged from said reach-rod.

3. In a look, a frame, an outer and an inner spindle, a latch-bolt and mechanism for operating the same, a locking-bolt, a rockshaft, said locking-bolt being connected to said rock-shaft, a reach-rod extending from said rock-shaft to a point adjacent the inner ends of both spindles, a key mechanism having a connection through said inner spindle with said reach-rod, said latch-bolt being independent of said key mechanism.

4:. In a lock, a frame, an outer and an innor spindle, a latch-bolt and mechanism for operating the same, a locking-bolt, a reachrod extending from said locking-bolt to adjacent the ends of said spindles, a rotatable rod in each of said spindles, knobs for each of said spindles, a key mechanism in each knob, each of said rods having an actuating-dog thereon, both of said dogs having an opera tive engagement with said reach-rod.

5. In a look, a frame, a locking-bolt, a plurality of separate actuating-dogs, bolt mechanism adapted to be engaged by both of said dogs, one independent mechanism connecting one of said dogs with one side of the frame, another independent mechanism connecting another of said dogs with the opposite side of the frame whereby said bolt may be operated from either side.

6. In a look, a frame, an outer and an inner spindle, a latch-bolt and mechanism for operating the same,a locking-bolt,a key mechanism havingaconnection extendingthrough said outer spindle, another key mechanism having a connection extending through said inner spindle, both of said connections cooperating with means for actuating said locking-bolt.

7. In a lock, a frame, an outer and an inner spindle, a latch-bolt and mechanism for operatingthe same,alocking-bolt,a key mechanism havinga connection extending through said outer spindle,.another key mechanism having a connection extending through said inner spindle, both of said connections cooperating with means for actuating said locking-bolt, said connections being independent of each other; but operative conjointly, and singly with said last means.
